“Pseudo reinfarction”: A consequence of electrocardiogram lead transposition following myocardial infarction

Abstract

Unexpected or bizarre new electrocardiographic changes should alert the physician to the possibility of lead transposition and, if in doubt, the electrocardiogram should be repeated. The classic form of limb lead transposition leading to the appearance of dextrocardia is well recognized. We report a patient with myocardial infarction where lead transposition led to a diagnosis of reinfarction and to the inappropriate use of thrombolytic therapy.
